Effects of microswitch-based programs on indices of happiness of students with multiple disabilities: a new research evaluation

The effects of microswitch-based programs on indices of happiness were evaluated with 9 students who had profound multiple disabilities. Each student received an ABAB sequence in which A represented baseline phases and B, intervention phases. During the latter phases, microswitches were used to enable the students to control preferred environmental stimulation with simple/feasible responses, such as hand-pushing and foot-lifting. Results show that all students increased microswitch responding during the intervention phases. Seven of them also had significant increases in indices of happiness, whereas the other 2 did not. In an attempt to shed some light on the reasons underlying the different outcomes, we examined procedural and methodological aspects of the study.     

Active surveillance: a potential strategy for select patients with small renal masses

Increased abdominal imaging has led to the significant incidental detection of clinically localized renal masses. While the gold standard remains surgical excision, mortality rates from kidney cancer remain relatively unchanged implying that a proportion of small renal masses may be indolent tumors that do not require surgical intervention. As a result, active surveillance has emerged as an alternative management strategy in select patients with significant competing risks. Although the contemporary literature characterizing the natural history of untreated small renal masses is limited, recent data demonstrate that many incidental renal masses demonstrate slow growth kinetics with a low rate of progression to metastatic disease over an intermediate time period. Prospective trials are necessary to define entry and intervention criteria for active surveillance protocols.     

Van der Woude syndrome: dentofacial features and implications for clinical practice

Background:  Van der Woude syndrome (VWS) is the most common clefting syndrome in humans. It is characterized by the association of congenital lower lip fistulae with cleft lip and/or cleft palate. VWS individuals have a high prevalence of hypodontia. Although caused by a single gene mutation, VWS has variable phenotypic expression. This study aimed to describe the range of clinical presentations in 22 individuals with VWS to facilitate its diagnosis.
Methods:  A retrospective study of 22 patients with a diagnosis of VWS was undertaken at the Australian Craniofacial Unit (ACFU) in Adelaide. Three extended families with affected members were included in the study cohort.
Results:  The overall prevalence of lip pits in this study cohort was 86%. Cleft phenotypes included bilateral cleft lip and palate (32%); unilateral cleft lip and palate (32%); submucous cleft palate (23%); and isolated cleft hard and soft palate (9%). Missing permanent teeth were reported in 86% of affected individuals.
Conclusions:  Submucous cleft palate in VWS may go undiagnosed if the lower lip pits are not detected. Associated hypodontia and resultant malocclusions will also require management by a dental team.     

Italian healthcare workers' views on mandatory vaccination

Background  

Mandatory vaccination has contributed to the success of immunisation programmes but voluntary vaccination allows people to be responsible for their own health. There are benefits from both policies and the arguments between them remain subject to debate within and without the scientific community, both nationally and internationally. The aim of this study is to assess the opinions of those who actually work in the Vaccination Service.     

Is ureteroscopy first line treatment for pediatric stone disease?

PURPOSE: We report our current outcomes for ureteroscopic management of pediatric stone disease. MATERIALS AND METHODS: We carried out a retrospective review of all ureteroscopic procedures for kidney or ureteral calculi performed between 2001 and 2005. Stone location and size, preoperative and postoperative stenting, intraoperative dilation, use of ureteral access sheath, stone-free rates and complications were noted. RESULTS: A total of 100 patients (58% female, mean age 13.2 years) underwent 115 procedures. Stones were located in the renal pelvis in 6% of patients, upper pole in 10%, mid ureter in 11%, lower pole in 17%, proximal ureter in 19% and distal ureter in 37%. Mean stone size was 8.3 mm (median 7.0), with a mean of 1.5 stones per patient. Preoperative stenting was used in 54% of patients, and a stent was placed postoperatively in 76%. Ureteral coaxial dilators and ureteral access sheaths were used in 70% and 24% of patients, respectively. There were no major intraoperative complications, although 5 patients required stent placement for ureteral perforation or extravasation. One patient had a ureteral stricture requiring ureteral reimplantation. Mean followup was 10.1 months (median 2.6). Stone-free rate was 91% on followup ultrasound, abdominal radiography or computerized tomography. Seven patients required staged ureteroscopic procedures to achieve stone-free status. While the number of percutaneous nephrolithotomy and shock wave lithotripsy cases remained stable, the number of ureteroscopic cases increased 7-fold during this period. CONCLUSIONS: Improved ureteroscopic access to stones throughout the pediatric urinary tract and stone-free rates that are comparable to the adult population have led to the adoption of ureteroscopy as first line therapy in children at our institution.     

Laparoscopy in paediatric urology: present status

The spectrum of laparoscopic surgery in children has developed dramatically; what was initially used as a diagnostic method to identify an impalpable testis is now commonly used for complex reconstructive procedures such as pyeloplasty. Laparoscopic orchidopexy and nephrectomy are well established and are used at many centres. Laparoscopic partial nephrectomy, adrenalectomy and dismembered pyeloplasty series have reported shorter hospital stays and operative times that are comparable with that of open techniques, and/or decreasing with experience. The initial experiences with laparoscopic ureteric re-implantation and laparoscopically assisted bladder reconstructive surgery are reported, with encouraging results for feasibility, hospital stay, and cosmetic outcome.     

Health impacts of family planning

Among the many effects of family planning is the influence ithas on mortality and morbidity in women and children throughthe mechanism of changing the number and spacing of children.There is a complex set of relationships between mother's age,parity, birth spacing and infant and child mortality and morbidity.Much effort has been put into untangling this web in the hopeof identifying clear causal connections, but for the most parton the basis of inadequate data. Rather than attempt to establishthe relative importance of child spacing as a cause of decreasesin mortality, this paper takes as its starting point that thereis a connection, and presents some possible causal mechanismswhich explain how short birth intervals and child mortalitycould be related. In addition the most frequently cited hypotheses-maternaldepletion and sibling competition-a third is examined-birthcrowding which, it is suggested, influences the pattern of thetransmission of infectious diseases and, in turn, mortality. In the field of maternal mortality, the data which could beused to quantify the benefits of family planning are in evenshorter supply; however, the causal connections are rather moreeasily identified. The final section combines parity-specificdata on maternal mortality with evidence of changes in fertilitypatterns brought about by family planning to assess how successfulwe can hope to be in reducing through birth control the numberof women who die in childbirth.     

Extending the evaluation of novel microswitch technology for small responses in children with profound multiple disabilities

This study extended the evaluation of microswitch technology (i.e., a position sensor and an optic device), recently introduced for chin and eyelid responses, with two new participants with profound multiple disabilities. The participants were girls of 12.5 and 4.0 years of age who did not possess any specific response that they could profitably use in their environment. The study was conducted according to an ABAB design with a 3-week postintervention check. The results showed that both participants increased their level of responding during the intervention phases and postintervention check compared to the baseline phases. This positive outcome was discussed in terms of (a) the apparent suitability of the technology and responses used in the study, (b) the beneficial implications for the participants, and (c) new developments in the area.
